Title: Process for the production of alumina
IPC: C01F7/40
Filed: 1927-10-26
Abstract: 279,870. Metallbank und Metallurgische Ges. Akt.-Ges., (Assignees of Schoenberg, G.). Oct. 26, 1926, [Convention date]. Alumina is prepared by fusing aluminiferous materials with reducing agents such as carbon in the presence of amounts of sulphides or of substances forming sulphides other than alkali metal sulphates, below about 3 per cent. Silicic and titanic acids are preferably first separated from the raw material by treatment with mineral acids, and the remaining mixture of iron and aluminium salts may then be transformed to oxide before treatment as above. The sulphur may be introduced as a gas. Sulphur-containing combustion gases may evaporate or decompose the mixture or iron and aluminium salts.
Patent GB-862192-A (GB)
Title: Process for the production of nitrogenous polycondensation products
IPC: C08G18/52
Filed: 1958-09-08
Abstract: Mono- or poly-primary or secondary aromatic amines or their hydroxyalkylation products containing at least two available hydrogen atoms are condensed with bis-b -hydroxy-alkyl sulphides at a temperature above 120 DEG  C. in presence of a dehydration catalyst. Depending on the starting materials, the products may contain sulphur and nitrogen bridging the carbon chains, or sulphur, nitrogen and oxygen, and may be linear, branched-chain or crosslinked.  Suitable amines are aniline, a toluidine, xylidene, cumidine, anisidine, nitraniline, chloraniline or anthranilic acid or ester; p-amino-phenol, a - or b -naphthylamine, a phenylene diamine, 4,41-diaminodiphenylmethane, 2,4- or 2,6-toluylene diamine, 4,41-diaminodiphenylsulphide or sulphone, benzidine, 3,31-dichlorobenzidine, 3,31-dinitrobenzidine. Amines containing other substituent groups which take no part in the reaction, e.g. alkoxy or sulphonic acid groups may also be used.  If desired the amines may be pre-reacted with an alkylene oxide, e.g. ethylene or propylene oxide to introduce one or more hydroxyalkyl group or chain. Suitable secondary amines are monohydroxyethyl aniline and N,N1-dimethyl-p-phenylene diamine.  Suitable sulphur-containing reactants are thiodiglycol, 1,1-(b -hydroxyethyl)-phenylene dithioether and corresponding compounds of the naphthalene and diphenyl methane series; HOC2H4SC2H4SC2HO4H; and <FORM:0862192/IV (a)/1> Suitable dehydration catalysts are aromatic sulphonic acids and their esters, e.g. p-toluene sulphonic acid; sulphuric acid; amidosulphonic acid; phosphoric acids; acid phosphates; organic phosphoric esters.  Water is distilled off during the reaction, if desired, under reduced pressure.  If unsaturated amines are incorporated in the reaction mixture, e.g. <FORM:0862192/IV (a)/2> <FORM:0862192/IV (a)/3> unsaturated products result.  Polyhydric alcohols, e.g. butanediol, diethylene glycol, hexanediol, glycerine, trimethylol propane or pentaecrythritol may be added to the reaction mixture.  Addition of 1 or 2% of maleic anhydride lessens discoloration of the products.  The products form salts and may be quaternized on the nitrogen and sulphur atoms.  In examples, equimolar proportions of thiodiglycol and (1) aniline, (2) N,N-dihydroxyethyl aniline, or (3) m-chloraniline are condensed together; (4) aniline, 4,41-diaminodiphenyl methane and thiodiglycol give a branched chain product, (5) m-toluidine, trimethylol propane, triethylene glycol and thiodiglycol give a branched chain product.

In Fig. 1, elements OR1-ORk can call for respective print programmes via amplifiers AP and terminals pal-pak which are scanned by a counter CP via a diode-resistor decoder V1, an acknowledgement being sent to the element via storage MP. MP also, via two amplifiers in series PI, produces printing of date, time, ticket number &c. The element, on receiving acknowledgment, selects sub-routine via amplifiers SP and terminals ps 1-psm connected tothe counter CP decoder V1 which can also call via amplifiers LCA for data from the element, this data being supplied in decimal form (after conversion from binary at DR1 or 2-out-of-6 at DR2) to letter or figure receiver amplifiers RL, RC respectively as appropriate. With the counter CP stationary, this data is scanned under control of an auxiliary counter CA, passing via its decoder V2 or V3 and its decoder V4 to letter or figure amplifiers LE, CH respectively. The data is then coded in 5-bit telegraph code at DR3 and sent via amplifiers AM and line M to printer IM, counter advance being stopped by a signal AR, and a read command CL going to the printer IM. A circuit GS, responsive to CH, LE, detects letter-figure and figure-letter shifts and sends appropriate signals to the printer IM. An amplifier RE (top left) permits re-read of data from a programme step already past. The counters CP, CA are driven (one at a time) from a circuit CDE which receives a signal SYN from the printer IM after reception by it of each character. Counters CK, CMP are used to control carriage return for formatting (counters CP, CA being inhibited).
